The remote host is affected by the vulnerability described in GLSA-200512-04 (Openswan, IPsec-Tools: Vulnerabilities in ISAKMP Protocol implementation)
The Oulu University Secure Programming Group (OUSPG) discovered that various ISAKMP implementations, including Openswan and racoon (included in the IPsec-Tools package), behave in an anomalous way when they receive and handle ISAKMP Phase 1 packets with invalid or abnormal contents.
Impact :
A remote attacker could craft specific packets that would result in a Denial of Service attack, if Openswan and racoon are used in specific, weak configurations.
Workaround :
There is no known workaround at this time.
